Application filed November 19, 1913. Serial No. 801,833.

To all whom it may concern Be it known that I, a citizen of the United States, residing at Bridgeport, county of Fairfield, State of Connecticut, have invented an Improvement in Cartridges, of which the following is a specification.

This invention relates to rim fire cartridges which require relatively light metallic shells, and has for its object to provide a cartridge having a bullet retained therein without crimping the mouth of the shell.

In the manufacture of cartridges it has heretofore been the practice to lock the bullets in place by crimping the mouths of the shells into the bullets. In practice, it is practically impossible to prevent a slight difference in the length of the shells. The crimping, however, takes place at exactly the same place without regard to the length of the shells, furthermore a rolled crimp if made deep enough to hold the bullet securely tends to deform the relatively soft bullet, and if the crimp is made light enough to avoid deformation of the bullet, the bullet is not held securely. fore, that when the crimping takes place, irrespective of deformation of the bullet, the amount of metal at the mouth of the shell that is forced into the bullet by the crimping operation varies slightly, the result being that some of the bullets are locked in the shells more tightly than others so that a I greater pressure is required in some instances than in others to force the bullet out of the shell when the explosion takes place, thereby affecting to a greater or less extent, the velocity of the bullet and tending to prevent extreme accuracy in shooting.

My present invention wholly overcomes this objection and makes for increased accuracy in shooting by insuring that all of the shells with an even tension without regard to the length of the shells. ThisI accomplish by doing away with the operation of crimping the ends of the shells, leaving the shells perfectly straight sided, and locking the bullets to the shells by a plurality of indentations in the shells by whichthe metal of the shells is forced 'into engagement with the V bullets.

Copies of this patent may be obtained for five cents each, by addressing the FRANK O. I-IOAGLAND,

It follows, there- 1 With the above stated object in view I have devised the novel cartridge of which the following description in connection with the accompanying drawing is a specification, reference characters being used to indicate the several parts.

Figure 1 is an elevation of my novel car tridge; Fig. 2 a partial longitudinal section thereof on the line 2-2 in Fig. 1, looking in the direction of the arrows, and Fig. 3 is a transverse section on the line 38 in Fig. 2, looking in the direction of the arrows.

10 denotes the shell, 1]. the bullet and 12 the powder. The length of the shell and the length and. contour of the bullet are wholly immaterialso far as the present invention is concerned. The powder is placed in the shell and the bullet is seated thereon in the usual manner. Instead, however, of crimping the mouth of the shell into the bullet to lock the latter in place, as has heretofore been the practice, I omit the operation of crimping entirely leaving the open end of the shell perfectly straight, and lock the bullet in place by making a plurality of indentations in the shell and forcing the in dented metal of the shell into the bullet, as at 13. The exact'number, shape, size or location of the indentations is wholly immaterial so far as the prlnciple of the invention is concerned, the gist of which lies in locking the bullet in the shell by indenting the metal of the shell into the bullet back of the open end of the shell and without crimping the mouth of the shell so that without regard to the length of the shells the bullets are secured therein with uniform tension and a maximum of accuracy in firing is attained.

Having thus claim:

A rim fire cartridge comprising a relatively light metallic shell and a bullet locked therein by a plurality of indentations of the metal of the shell into the bullet back of the mouth of the shell.

In testimony whereof I affix my signature in presence of two witnesses.

FRANK O. HOAGLAND.
